His first film appearance was as a sailor in We the Living (1942), but Vallone was not interested in an acting career. Nevertheless, he was cast as a soldier competing with Vittorio Gassman for the love of Silvana Mangano in Riso amaro (Bitter Rice) (1949). The film became a neo-realist classic and Vallone was launched on an international career. In 2001 he published his autobiography, L'alfabeto della memoria, with Gremese (Rome).
